I've always been very picky with puzzle games, so much so that there's very few that I really enjoy thoroughly. This is one of those games that I enjoy thoroughly. It's very well designed, has a heck ton of puzzles and yet somehow nearly every single one of them is a unique challenge.
Thanks you Northernlion for showcasing this game, it's really just incredible.
This is exactly what it says on the tin, with tons upon tons of customization to fit whatever FPS game you fancy. I've had it since the first alpha and even though it was already great then, its functionality and customizability has been steadily improving.
It turns boring aim practice into a more engaging package, and makes improvement more tangible by way of challenge scores. For 10 bucks it's pretty much a steal.
If you liked quake, definitely check out this game. Even though it's in early alpha, it's already really polished and works amazingly. Every update has been amazing so far, and I'm expecting this trend to continue.
